1 Claim.

The present invention pertains to a novel valve designed particularly to permit the admission of air, gas, or any liquid, or fluid, simultaneously into two or more separate reservoirs, tanks, or chambers, and to automatically shut ofi all outlets from the inlet and from one another.

The reservoirs, tanks or chambers to be filled can be separate, or inside one another.

The said valve is so constructed that it has a single inlet and as many outlets as the number of reservoirs to be filled. The opening of the valve by back pressure from any or all the reservoirs or from weakening of the spring and 1eaking at the valve seat, is prevented by a safety locking device.

Figure I is a longitudinal section through the axis of a valve used to supply two chambers; this figure shows valve open;

Figure II is a cross-section at the side outlet numbered 20 on Figure I;

Figure HI is a cross-section through stem guides numbered 1 on Figure I;

Figure IV is a cross-section through the parts 8 (Fig. I) in the sides of the safety lock nut 9;

Figure V is an axial section of the valve cap;

Figure VI is a cross-section through the key top of the cap shown on Figure V;

Figure VII is a modified arrangement of Fig. I showing a valve used to supply a number of chambers 20';

Figure VIII is a view of the seat of valve shown on Figure VII;

Figure IX is a perspective View of the safety lock nut 9.

The device consists essentially of a tube I and a valve body 2 within tube i (Fig. I), leakage around the valve body being prevented by gaskets and M which are pressed against their seats 4 and I3 by the screw head [9, which also withdraws the body from the tube when necessary. The annular space between the valve body 2 and tube 1 and between gaskets 5 and [4 permits the valve body to be replaced in the tube in any radial position without the necessity of aligning the outlet hole from i? with outlet 20.

The screw head [9 is attached to valve body 2 in such a manner that IE is free to rotate in relation to 2. At top of screw head i9 is the inlet designated H3 (Fig. I). At the opposite end of valve body 2, when the Valve is open, is the space H common to the two annular passages I! and I8 leading to outlets and A single obturator I2 closed by spring 6, automatically shuts ofi the passages l7 and I8 from the source of supply and from one another.

All outlets are supplied from space H situated between valve seat and obturator l2.

Obturator I2 is carried on stem 3 which is prevented from rotating by guide lugs l sliding in grooves 22 in the valve body 2, and from lateral displacement by guide lugs 1 and IS.

The safety lock nut 9, the upper part of which is threaded on the inlet end of stem 3, pulls the obturator l2 tightly to its seat, sealing it against leakage due to weakening of spring 6, minor defects on surface of obturator, or back pressure.

The lower part of safety lock nut 9 is cored out, having lateral ports as at 8 for passage of air, gas, liquid or fluid, from the inlet to the valve body 2.

The inlet it is covered with a screwed cap (Fig. V) the top of which provides a key 5 for operating the safety lock nut 9.

After the safety lock nut 9 has been unscrewed by the cap key 15, the air, gas, liquid or fluid, under pressure, enters at inlet Ill, passes through ports 8 (Figs. I and IX) into the valve body 2, and, the obturator I2 being open by fluid pressure or otherwise, penetrates into the space H and reaches the independent reservoirs or chambers through outlets 2!! and 2 I.

When the pressure is relieved from the inlet 10 (no other positive action being applied on stem 3), the valve automatically closes under the action of the spring '6. The chambers connected to outlets 20 and 2| are then automatically cut ofi from each other and from inlet In by the obturator l2.

The modifications illustrated in Figure VII and VIII are for valves of any number of outlets greater than two. The principle of operation is identical with the two outlet valve shown in Figure I.

In Figures VII and VIII, the chief structural difference is that outlets 28 have individual passages i'l' alongside the inlet passage in the valve body 2', in place of the annular passage I1, Fig. I, with their seats arranged around the perimeter of the inlet seat. The body 2 is further modified to accommodate a single gasket It which is pierced with holes corresponding to the outlets 20. This construction may be used for valves where balanced back pressure on the obturator is not required.

The following important features result from the construction shown in Figure I:

(a) The back pressure from any and all reservoirs is concentrically balanced around the stem irrespective of the relative back pressures from the reservoirs;

to be understood that various alterations in the details of the construction may be made without departing from the spirit or scope of our invention as indicated by the appended claim.

Having thus fully described our invention, what we claim and desire to secure by Letters Patent is: A multiple outlet valve comprising a hollow,

open ended cylindrical casing having a plurality 20 of inwardly extending shoulders, a valve assembly mounted within the Casing, said assembly comprising an open ended tubular seat member having a plurality of washers thereon for sealing engagement with said shoulders, the tubular member being spaced from the portion of the inner wall of the casing between the shoulders to provide an annular chamber, an outlet opening through the said casing wall portion, a second annular chamber in one end of said tubular member concentrically arranged within said first chamber and having one end open, a port in a wall of the second chamber providing communication between the two chambers, the inner wall of said second annular chamber defining an outlet for the passage through the tubular seat member, a spring pressed valve member normally closing the said open end of the second annular chamber and the outlet of the tubular seat member.
